'taskmanager' is a Perl/Tk application written to be platform-independent and hopefully not require any more external modules than absolutely necessary. In short, it is a manager for tasks, actions making up those tasks, and a logging facility to track the status/progress.

Gtk2-Perl is the collective name for a set of Perl bindings for GTK+ 2.x and various related libraries. These modules make it easy to write GTK+ and GNOME applications using a natural, perlish, object-oriented syntax.

metaf2xml can download, parse, and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), and BUOY observations, and store the data as XML. XSLT style sheets convert it to plain language, as HTML or text. Current weather data from NOAA and other sources can be fetched and displayed.

Foswiki is wiki software, supporting the editing
of Web pages in an ordinary Web browser by end
users. What makes Foswiki special is that it
supports the embedding of active and passive
macros that enhance the page content (e.g. with
global or dynamic information) and allow end-users
to build applications that store and process data
in a structured manner.

Config-Model provides a framework for editing and validating the content of any configuration file or data. With a configuration model (expressed in a data structure), Config-Model provides a user interface and a tool to validate configuration. An optional graphical (Perl/Tk) or curses interface can be used to edit configuration data that will be validated according to the user-provided model. Config-Model includes a model example for fstab and a small fstab demo.

Triceps is an innovative embeddable Complex Event Processing (CEP) system. It can be thought of as an in-memory database driven by triggers, or a data-flow machine working on a stream of events, or a spreadsheet on steroids. The major architectural advantages of Triceps include the direct use of procedural logic (as opposed to all-SQL systems), support of both compiled and general scripting languages (C++, Perl), light weight, and easy extensibility.

Class::EHierarchy is intended for use as a base class for custom objects. The objects need one or more of the following features: orderly bottom-up destruction of objects, opaque objects, class-based access restrictions for properties and methods, primitive strict property type awareness, and alias-based object retrieval.
